malwarebytes.org not accessible

Hi guys,
This happened roughly two months ago, just out of the blue.
I previously had Tomato 1.23.
Configured with OpenDNS.

Now, at one point, www.malwarebytes.org does not load anymore, even with two other computers in the household. So I did a erase nvram, upgraded to 1.25, and still no luck. I cannot ping the site, but I can traceroute.
What did work was having my computer have direct internet access to the cable modem.

Anyone shed some light as to why this randomly occurred?
I can still update the application 'malwarebytes', but the site itself will not load.

nope.
My host file is perfectly fine. At first, I thought it was malware, now that that's not the case, I don't know what else to think of it.
The site worked two months ago, then one day it's not loading.
